.::: Install jemalloc Memory Allocation MariaDB 12 in Almalinux 10 & Ubuntu :::.

 

 

1. check mariadb memory allocation

SELECT @@hostname, @@version_comment,@@version;
SELECT @@hostname AS hostname,@@version AS mariadb_version, @@version_malloc_library AS memory_allocator;
 

2. Install epel release 

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-10.noarch.rpm -y

3. Install jemalloc 
 
# redhat
yum install jemalloc -y

# ubuntu
apt install -y libjemalloc2

.::: Enable Dynamic Data Masking (DDM) in MariaDB 12 using view, list view :::.

 

Oh, kalau MariaDB, beda dengan SQL Server. MariaDB tidak memiliki fitur Dynamic Data Masking (MASKED WITH) bawaan seperti SQL Server.

Untuk tabel customer Anda, cara yang paling umum adalah membuat VIEW yang menampilkan data sudah dimasking. Data asli tetap tersimpan di tabel.

1. Data asli

CREATE TABLE customer(
    KODE_CUSTOMER CHAR(6),
    NAMA_CUSTOMER VARCHAR(30),
    ALAMAT_CUSTOMER VARCHAR(30),
    KOTA_CUSTOMER VARCHAR(15),
    TELEPON_CUSTOMER VARCHAR(15),
    PRIMARY KEY(KODE_CUSTOMER)
);

SELECT * FROM customer;

2. Buat VIEW untuk data yang dimasking

CREATE VIEW v_customer_masked AS
SELECT
    KODE_CUSTOMER,
    NAMA_CUSTOMER,
    CONCAT(
        LEFT(ALAMAT_CUSTOMER, 3),
        '********'
    ) AS ALAMAT_CUSTOMER,
    KOTA_CUSTOMER,
    CONCAT(
        '########',
        RIGHT(TELEPON_CUSTOMER, 4)
    ) AS TELEPON_CUSTOMER,
    '********' AS TELEPON_CUSTOMER_ALL
FROM customer;
 

.::: Enable Dynamic Data Masking (DDM) SQL Server MSSQL 2025 include using view :::.

 

1. Tabel awal

 
CREATE TABLE customer(
    KODE_CUSTOMER CHAR(6),
    NAMA_CUSTOMER VARCHAR(30),
    ALAMAT_CUSTOMER VARCHAR(30),
    KOTA_CUSTOMER VARCHAR(15),
    TELEPON_CUSTOMER VARCHAR(15),
    PRIMARY KEY(KODE_CUSTOMER)
);
 

2. Tambahkan Dynamic Data Masking for telepon & alamat 

ALTER TABLE customer
ALTER COLUMN TELEPON_CUSTOMER
ADD MASKED WITH (FUNCTION = 'partial(0,"XXXXXXX",4)');

ALTER TABLE customer
ALTER COLUMN ALAMAT_CUSTOMER
ADD MASKED WITH (FUNCTION = 'partial(3,"XXXX",3)');

ALTER TABLE customer
ALTER COLUMN KOTA_CUSTOMER
ADD MASKED WITH (FUNCTION = 'default()');
